The following is a copy of an old message in this newsgroup from
Liam Gumley (I think). It worked at least for Redhat 6.0
I also heard that RSI has released a version 5.2.1 for Linux
in which the installation problem was fixed. You might want to
have a look at html://www.rsinc.com

To get IDL 5.2 to work under Redhat 6.0, a patch is required. The
instructions below were posted by Olivier Archer
(mailto:oarcher@ifremer.fr), and have been used here successfully for
two different Linux systems.

Here's another way to get around the problem.
The goal is to define the setfpucw function


void __setfpucw(void)
void __libc_init(void)
void _dl_symbol_value()

Compile it:
#gcc -fPIC -c __setfpucw.c
#ld -shared -o __setfpucw.so -assert pure-text __setfpucw.o

define the LD_PRELOAD environnement variable before launching
#export LD_PRELOAD=/?/?/__setfpucw.so
